An entomological surveillance system based on open spatial information for participative dengue control Anais da ABC (AABC)
Regis,Leda; Souza,Wayner V.; Furtado,André F.; Fonseca,Cláudio D.; Silveira Jr.,José C.; Ribeiro Jr.,Paulo J.; Melo-Santos,Maria Alice V.; Carvalho,Marilia S.; Monteiro,Antonio M.V..
Aedes aegypti is a very efficient disseminator of human pathogens. This condition is the result of evolutionary adaptations to frequent haematophagy, as well as to the colonization of countless types of habitats associated with environmental and cultural factors that favor the proliferation of this mosquito in urban ecosystems. Studies using sensitive methods of monitoring demonstrate that the methods of surveillance used in the Brazilian program do not show the high degrees of the infestation of cities by this vector. To increase the capacity of the health sector, new tools are needed to the practice of surveillance, which incorporate aspects of the vector, place and human population. We describe here the SMCP-Aedes - Monitoring System and Population...

Analysis of toxicity on Bacillus sphaericus from amazonian soils to Anopheles darlingi and Culex quinquefasciatus larvae Acta Amazonica
Litaiff,Eleilza de Castro; Tadei,Wanderli Pedro; Porto,Jorge Ivan Rebelo; Oliveira,Ila Maria de Aguiar.
Bioassays under laboratory conditions aiming to determine the larvicidal activity of Bacillus sphaericus were carried out on Anopheles darlingi and Culex quinquefasciatus. In order to estimate the toxicity through median lethal concentration (LC50) and the relative potency of the strains to B. sphaericus standard strain 2362, probit analysis was performed utilizing the POLO-PC program. The findings of LC50 pointed out high effectiveness on strains IB15 (0.040 ppm), IB19 and S1116 (0.048 ppm), IB16 (0.052 ppm) and S265 (0.057 ppm). Strain IB15 presented nearly 50% more potency than strain 2362 in bioassays conducted on A. darlingi. It was observed that IB16 and S1116 strains were the most powerful against C. quinquefasciatus, showing to be about 300-400%...

Bioactivity of the latex from Parahancornia amapa (Apocynaceae) on the development of Rhodnius nasutus (Hemiptera, Reduviidae, Triatominae) under laboratory conditions Rev. Bras. entomol.
Lopes,Marcio B. P.; Mendonça,Paloma M.; Mallet,Jacenir R. S.; Carvalho,Mário G.; Queiroz,Margareth M. C..
Bioactivity of the latex from Parahancornia amapa (Apocynaceae) on the development of Rhodnius nasutus (Hemiptera, Reduviidae, Triatominae) under laboratory conditions. The aim of this study was to verify the effects of the methanolic fraction of the latex from Parahancornia amapa (Apocynaceae) (PALAM) on individuals of the species Rhodnius nasutus Stål (Hemiptera, Triatominae). Many of the insects treated with the substance presented deformities and these may interfere in the feeding and possibly hinder the reproductive capacity. They also presented significant mortality during the molt when compared to the control group, noting a gradual increase in mortality. The treated insects also presented delayed nymphal development (5th instar) and higher adult...

Insecticidal activity of Leptodactylus knudseni andPhyllomedusa vaillantii crude skin secretions against the mosquitoes Anopheles darlingi andAedes aegypti J. Venom. Anim. Toxins incl. Trop. Dis.
Trindade,Frances TT; Soares,Ângela A; Moura,Andréa A de; Rego,Tiago B; Soares,Andreimar M; Stábeli,Rodrigo G; Calderon,Leonardo A; Almeida e Silva,Alexandre de.
Background Mosquitoes are important vectors of several diseases, including malaria and dengue, and control measures are mostly performed using chemical insecticides. Unfortunately, mosquito resistance to commonly applied insecticides is widespread. Therefore, a prospection for new molecules with insecticidal activity based on Amazon biodiversity using the anuransLeptodactylus knudseni andPhyllomedusa vaillantii was performed against the mosquito speciesAnopheles darlingi and Aedes aegypti.Methods The granular secretion from anuran skin was obtained by manual stimulation, and lethal concentrations (LCs) for larvicidal and adulticidal tests were calculated using concentrations from 1-100 ppm. The skin secretions from the anuran species tested caused...

Prospects for area-wide integrated control of tsetse flies (Diptera:Glossinidae) and trypanosomosis in sub-Saharan Africa Rev. Soc. Entomol. Argent.
Vreysen,Marc J.B..
Countries in sub-Saharan Africa are among the least developed in the world and hunger and poverty remains widespread in most of the rural communities. Reducing hunger and chronic under nourishment through the introduction of productive livestock as a source of traction and manure for crop production, transport, milk and meat is deemed to be a fundamental first step towards better rural development. The presence of the tsetse fly in one third of the African continent and the disease trypanosomosis it transmits is considered the major barrier to the development of productive livestock. Despite the yearly administration of 35 million doses of trypanocidal drugs (at US$ 1 per dose), African farmers lose 3 million cattle every year to the disease and annual...

Spatial evaluation of larvae of Culicidae (Diptera) from different breeding sites: application of a geospatial method and implications for vector control Rev. Bras. entomol.
Piovezan,Rafael; Azevedo,Thiago Salomão de; Von Zuben,Cláudio José.
Spatial evaluation of Culicidae (Diptera) larvae from different breeding sites: application of a geospatial method and implications for vector control. This study investigates the spatial distribution of urban Culicidae and informs entomological monitoring of species that use artificial containers as larval habitats. Collections of mosquito larvae were conducted in the São Paulo State municipality of Santa Bárbara d' Oeste between 2004 and 2006 during house-to-house visits. A total of 1,891 samples and nine different species were sampled. Species distribution was assessed using the kriging statistical method by extrapolating municipal administrative divisions. The sampling method followed the norms of the municipal health services of the Ministry of Health...

Synthesis of new α-amino nitriles with insecticidal action on Aedes aegypti (Diptera: Culicidae) Rev. Bras. entomol.
Rueda,Andrés G.; Carreño Otero,Aurora L.; Duque,Jonny E.; Kouznetsov,Vladimir V..
Abstract Aedes aegypti is the principal vector of arboviral pathogens that may cause diseases as dengue fever, chikungunya and zika. The harmful environmental effects of commercial pesticides coalesced with the development of insecticide-resistant populations encourage the discovery and generation of new alternative products as a tool to reduce the incidence of vector-borne diseases. In this work, through the classic three component Strecker reaction of commercial benzaldehydes, cyclic secondary amines and KCN, a new series of nine α-amino nitriles, girgensohnine analogs, has been synthetized and screened for larvicide and adulticide properties against A. aegypti, one of the dominant vectors of dengue, chikungunya and zika in tropical and subtropical areas...

Viruses vector control proposal: genus Aedes emphasis BJID
Reis,Nelson Nogueira; Silva,Alcino Lázaro da; Reis,Elma Pereira Guedes; Silva,Flávia Chaves e; Reis,Igor Guedes Nogueira.
Abstract The dengue fever is a major public health problem in the world. In Brazil, in 2015, there were 1,534,932 cases, being 20,320 cases of severe form, and 811 deaths related to this disease. The distribution of Aedes aegypti, the vector, is extensive. Recently, Zika and Chikungunya viruses had arisen, sharing the same vector as dengue and became a huge public health issue. Without specific treatment, it is urgently required as an effective vector control. This article is focused on reviewing vector control strategies, their effectiveness, viability and economical impact. Among all, the Sterile Insect Technique is highlighted as the best option to be adopted in Brazil, once it is largely effectively used in the USA and Mexico for plagues related to...
